Kuber and his people moved as far as the region of Thessaloniki. He decided to settle together with the Sermesianoi in a plain and sent his envoy to the Byzantine Emperor, whom the Miracles of Saint Demetrios did not name, to request his permission. The emperor gave his consent and ordered the nearby Slavic tribe of the Dragovites to supply Kuber and his people with food. However, Kuber's people still wanted to go back to their ancestral homes and started to disperse. Fearing of the decline of his power base, Kuber asked the emperor to forbid the Sermesianoi to leave the plain and to confirm Kuber's position as their ruler. His request seems to have been rejected, because he attempted to seize Thessaloniki, taking advantage of a civil war in the city. However, Saint Demetrius unmasked Kuber's agents who tried to open the gates of Thessaloniki, hindering him from entering the city, according to the saint's hagiography. There is no more information of Kuber's life.
